Mystery spoon set - possibly Scandinavian or German?

Hi everyone!
I bought this spoon set a few days ago and they just arrived. The seller didn't know anything about them, so I've been trying to do some research to find out where they're from, how old they are and what they're made of.
The only thing I know is that I bought them in Denmark and other similar (/identical) sets have been found in Denmark and Sweden. My guess is that they are gilded silver plate, but the gold has worn off a bit in many places. Apparently the face that looks like a baby or a cherub is called a Putti face?
They have no marks indicating, maker, year or material - unlike the set in this thread which had 'NS' stamped on them. The box is also without any information (I don't know if it's the original box).
I only cleaned 5 out of the six spoons so far because I quite liked that you can clearly see the difference and the oxidized one actually photographs more clearly.
Does anyone know anything that might help shed some light on these spoons?
